Abstract: Cameras provide an easy-to-deploy and information-rich datastream for a wide range of ubiquitous sensing and health monitoring applications. However, their unrestricted operation often captures personally identifiable information (PII), preventing their use in privacy-sensitive settings, such as the home, workplace, and hospitals. This disclosure proposes pairing RGB and thermal imaging to robustly detect and remove PII (e.g., an individual's face, skin color, gender, body shape, etc.,) from images before they are stored or sent off the device. A dual camera prototype includes an onboard embedded GPU capable of performing real-time privacy sanitization tasks at 8FPS at under 5 W power consumption. Results show that in the most fail safe settings the system completely removes all PII.

Abstract: Plasmonic nanostructures function as an antenna-reactor nanostructure to focus and convert light into thermal/chemical energy, and thus have significant potential for sustainable solar water disinfection. However, the insufficient energy harvesting efficiency resulting from inconsistent nano-features linked with arrangement and scaling is a persistent challenge. An integrated optofluidic fabrication method is presented to produce a high density integrative plasmonic dimer array to enhance solar water disinfection. The plasmonic dimer array is constructed by a combined fabrication of self-assembly monolayer method and block-co-polymer lithography approaches. This combination leads to a two-dimensional hexagonal array of dimer structures consisting of 1.3 nm nanogap. The uniformity and high density of the nanogaps in the plasmonic dimer array allows strong light focusing and a rapid and highly efficient harvesting of photothermal energy at visible and near-infrared region.

The progressive cellular architecture consists of a series of heterogeneous micro-gas chromatography cells. Each individual cell targets vapor species within a specific volatility range by using a unique combination of a preconcentrator and a separation column.

Valves may inadvertently absorb or adsorb and subsequently release target chemical analyte molecules, thereby interfering with quantitative analysis. Therefore, the inlet to the cells is configured without a valve.

Abstract: Methods and systems perform magnetic resonance fingerprinting (MRF) by obtaining scan data of a sample at a low-resolution over a k-space and obtaining other scan data at a high-resolution over the k-space. This scan data may be captured over the same regions, different regions, or where one scan data is captured over a sub-region of the other. The low-resolution and high-resolution scanning is repeated according to a scanning ratio between the first scan data and the second scan data to generate interleaved low-resolution and high-resolution scan data. From that interleaved low-resolution and high-resolution scan data, high-resolution tissue property maps of the sample are generated.
